Question: There is a city that a prominent adult contemporary band from this period, along with the Eagles and the person who said the results were racist, was named after. How close is Wrigley Field to the source of drinking water for this city?
Context: Document 1: Wrigley Field: In April and May the wind often comes off Lake Michigan (less than a mile to the east), which means a northeast wind ``blowing in ''to knock down potential home runs and turn them into outs. In the summer, however, or on any warm and breezy day, the wind often comes from the south and the southwest, which means the wind is`` blowing out'' and has the potential to turn normally harmless fly balls into home runs. A third variety is the cross-wind, which typically runs from the left field corner to the right field corner and causes all sorts of havoc. Depending on the direction of the wind, Wrigley can either be one of the friendliest parks in the major leagues for pitchers or among the worst. This makes Wrigley one of the most unpredictable parks in the Major Leagues.
Document 2: Water cribs in Chicago: The water cribs in Chicago are structures built to house and protect offshore water intakes used to supply the City of Chicago with drinking water from Lake Michigan. Water is collected and transported through tunnels located close to 200 feet beneath the lake, varying in shape from circular to oval, and ranging in diameter from 10 to 20 feet. The tunnels lead from the cribs to one of two water purification plants located onshore, the Jardine Water Purification Plant (the world's largest) and the Eugene Sawyer Water Purification Plant, where the water is then treated before being pumped to all parts of the city as well as 118 suburbs.
Document 3: Adult contemporary music: The Hot 100 and Easy Listening charts became more similar again toward the end of the 1960s and into the early and mid-1970s, when the texture of much of the music played on Top 40 radio once more began to soften. The adult contemporary format began evolving into the sound that later defined it, with rock-oriented acts as Chicago, The Eagles, and Elton John becoming associated with the format.
Document 4: American Idol: Much media attention on the season had been focused on the three black singers, Fantasia Barrino, LaToya London, and Jennifer Hudson, dubbed the Three Divas. All three unexpectedly landed on the bottom three on the top seven result show, with Hudson controversially eliminated. Elton John, who was one of the mentors that season, called the results of the votes "incredibly racist". The prolonged stays of John Stevens and Jasmine Trias in the finals, despite negative comments from the judges, had aroused resentment, so much so that John Stevens reportedly received a death threat, which he dismissed as a joke 'blown out of proportion'.
